Abstract
毗邻雄安新区的苏桥地下储气库群是目前世界上储层埋藏最深、运行压力最高的地下储气库群,其注采工程面临着一系列的技术难题和安全风险.为此,从自然环境、社会环境和工程建设等3个方面对该地下储气库群进行了分析.结果表明:①该地下储气库群地理位置较为特殊,存在着受自然灾害影响的风险;②该地下储气库群位于京津冀中心地带,存在着一定的社会风险;③该地下储气库群地质条件复杂,在施工建设过程中也存在着一定的风险.由此构建了由三级安全保障系统和三级安全控制系统组成的保障体系:①基于完井工程、井下管柱和井口安全的三级安全保障系统,从源头上保证该地下储气库群强注强采的安全;②在地下储气库安全控制设计中,提出了从单井到地下储气库群一体化系统的设计理念,建立了单井就地独立控制、井场集中联动应急安全控制、远程统一控制等三级控制系统.结论认为:三级安全保障系统和三级安全控制系统的应用,有力地保障了该地下储气库群的平稳运营.
The Suqiao underground gas storage (UGS) group,deepest in the world and adjacent to the Hebei's Xiongan New Area,is operating under such ultra-high pressures that the involved injection-production engineering project is meeting great challenges and safety risks.In view of this,the challenges and risks were first analyzed from the aspects of natural setting,social environment and project construction.Due to their peculiar geographical location,especially in the Beijing-Tianjin-Hebei Center,both natural disasters and social risks to some degree pose threats on the project.Besides,because of their complicated geological conditions,great challenges will have to be encountered in the project construction.Therefore,three-level safety guarantee and control systems were thus established to efficiently guarantee the safe and smooth operation of the whole project.The three-level safety guarantee system based upon well completion,downhole tubing strings,and wellhead control primarily ensures the safety of intensive injection and production;and the integrated three-level safety control system from an individual well to the UGSs realizes a single well's local independent control,the centralized emergency control on the well site,and the remote control in the master-control room.
